Betsy, 
My kids and I transplanted several hundred 2-yr old seedlings of Major &
Posey (northern pecan), back in 2000, into a 100-ft wide CRP riparian
bufferstrip that runs the length of the farm - about 7 acres in total.
Other than once or twice a year mowing, they've received little to no care. 
While mowing last weekend, I noticed that ONE tree has nuts this year.
So...15-20 years is probably about as soon as you'll see nuts - though with
some vegetation control and fertilization, you might get there sooner than
mine did. 
Named-parentage black walnut seedlings, planted in that riparian bufferstrip
at the same time as the pecan seedlings have been bearing good crops of nuts
for 5 or 6 years now.

Thank you Lucky, the differences in ploidy among species is reassuring.

I will plant them out next year in their permanant site and we shall have
nuts to evaluate- I guess in about 15 years?
